Designating The Power Splitter Reference Output; Zeroing And Calibrating The Power Sensor; Characterizing The Rf Source 1 Power (Direct) - National Instruments PXIe-5693 Calibration Procedure

Designating the Power Splitter Reference Output

Designate one of the two outputs of the power splitter as the reference output. Consistently use
the same output as the reference output throughout the characterization and verification
procedures.

Zeroing and Calibrating the Power Sensor

1. Connect channel A of the power meter to power sensor A.
2. Connect channel B of the power meter to power sensor B.
3. Zero and calibrate the power sensors using the built-in functions in the power meter.

Characterizing the RF Source 1 Power (Direct)

Zero and calibrate the power sensor using the procedure in the Zeroing and
Note
Calibrating the Power Sensor section prior to starting this procedure.
1. Connect the RF source 1 output directly to the power sensor B input.
2. Connect power sensor B to channel B of the power meter. Figure 1 shows the completed
equipment setup.
